Our M7DH45B2A humidifier is now freezing up. We purchased it 14 mos. ago and it has worked FINE. Now it freezes up and it's frustrating. The room temp is the same in our basement as it always has been. 66 degrees. I was told that some models will not work properly in temps. less that 65 degrees. But the room temp here HAS NOT changed since we first used the Dehumidifier.

Daveschevy2 hit the nail on the head. I had the exact same freezing up problem. I opened up the case and found the temperature sensor rusted and just hanging by its wire. I used my Dremel tool to clean the rust then I used a piece of wire to tie it back onto the coil in the correct position. Thank you for the fix.

I have the same dehumidifier and it does the same thing. but I was able to fix mine. It was not low on refridgerant. There is a temp. sensor clamped to the evaporater coil with a thin metal clip. The clip rusted out and the sensor fell out of position. I used a small stainless steel hose clamp and clamped the sensor back into position. It now works fine

I have the same freeze-up problem...I assume it must be a small leak or all the coolant would be lost. Is this a problem that can be fixed by trying to patch the leak?
